MEANS FOR WASHING- OR DYEING MATERIAL.

Application filed December 12, 1925. Serial m. 18,093.

This invention relates to a machine for washing or dyeing material, especially material of a strand-like character such as artificial silk threads, and has for its main object and feature the rovision of means for carrying on the washing or dyeing operation in a more expeditious manner than has heretofore been possible.

In the accompanying drawings the invention is disclosed in a concrete and preferred form in which:

Fig. 1 is a general view, partly in elevation and partly in section of a machine embodying the invention showing two tanks.

Fig. 2 is a view partly in elevation and partly in section of one of the tanks and devices associated therewith.

Fig. 3 is a View, in elevation, looking in the direction of arrow 3 of Fig. 2.

Fig. 4 is a vertical transverse section of a rotatable member used in connection with the device.

Fig. 5 .is a longitudinal sectional view through one of the work holders.

Fi 6 is a transverse sectional view substantially on the plane of line 66 of Fig. 5

Fig. 7 is a transverse sectional view substantially on the plane of line 7 -7 of Fig. 5.

Fi 8 is a transverse sectional view substantially on the plane of line 88 of Fig. 5.

Referrin now to the drawings, Figs. 4 and 5, 1 in icates a hollow erforated spool which carries the convolutions of material 2, and this spool is mounted on a hollow perforated work holder 3 that communicates with the interior of a member 4 from which extends exhaust pipe 5 to which'a suction device as 6 Fig. 1) is attached. Member 4 is containe within a tank 7 (Fi 2 and 3) containing a body of treating fluid 8, and the exhaust pipe 5' leads from the interior of member 4 to a point outside the tank. It will therefore be seen that, suction being applied by device 6 to pipe 5, the treating flllld will be carried over the work or throu h the convolutions, into the interior of t e work holder and out throu h the exhaust.

Coming now to a more etail descri tion of the device it will be seen that mem er 4 is a rotatable member suitably mounted within the tank and rotated as by means of worm 9 and worm gear 10. Member 4 may be constructedin many different ways, but, as here shown, it consists of two halves bolted together as at 11, said halves forming a chamber 12. Mounted on the exterior of said member 4 are preferably a plurality of work holders 3, each of which may conveniently be constructed as follows: 13 indicates a bracket which carries a tubular extension 14 having perforations 15. The bracket is secured to member 4 by bolts or screws passing through openings 16, and, by reason of inlets 17 in member 4, the intenor of the work holders communicate with chamber 12. Preferably, tubular extension 14 is of such amplitude that two spools 1 may be carried in tandem as shown in the drawings, and these spools, which may conveniently be perforated cylinders of sheet material, are slipped over the tubular exten- S1011, packing rings or gaskets 18 between and at the ends of the spools bein used to space and seal the parts, after whic an end piece 19 is secured in position by means of screw 20 entering bridge member 21 of the tubular extension. By the foregoin means it will be seen that the treating fiui cannot enter the work holders except by passing through the convolutions. As shown in the drawings, the arrangement of work holders is preferabl in duplicate, there being a series of wor holders extending from each face of member 4.

Exhaust pipe 5 is here shown as being a stationary pipe and extends from the lower end of the tank and out throu h the bearings and shaft 22 of member 4. he suction device 6 may, of course, be of any suitable character but preferably an ejector is used, fluid (such as water) under pressure comin through pipe 23 and in assing through ejector 6 creates a suction in a well-understood manner. The treating fluid may be introduced into the tank by means of pipe 24, and to empty the tank a waste pipe 25 controlled by valve 26 is used.

It will be noted, particularly from Fig. 4, that the sidewalls of the rotatable member slope from its axis of rotation toward its peri hery, and that said member has central y of its interior, between the sidewalls, an annular clearance space 25. Non-rotatable ipe 5 extends into the member in line wit its axis of rotation and then interiorly of said member, in the plane of said clearance space, toward the periphery of the member in the direction of the bottom of the tank. 26 indicate lateral outboard bearings and it will be noted that the workholders extend laterally adjacent the periphery of said rotatable member.

In Fig. 1 the equi ment is double, that is two tanks complete y equipped are shown, but that, as will be understood, is a mere convenience.

The operation of the complete apparatus consists in rotatin member 4 within the tank and at the same time actuating ejector 6, the result being to draw the treating fluid over the work, into the rotatable member and out of the machine. When the machine is used to wash the acid from the threads the foul water may be wasted, but if the machine is used for dyeing, the dye may be returned through plpe 24 or otherwise. If it is desired that the body of liquid in the tank shall reach above bearings 22 it will be understood that said bearings and shafts will have suitable packing to prevent outflow of fluid. The tank may be either completely or partially filled with treating fluid. In case the tank is completely filled the work holders will be constantl immersed and a relatively large amount ot treating fluid will be constantly drawn out of the tank. In handlin certain materials it may be desirable to lessen tha flow of the treating fluid by drawing air in at the same time. This can be accomplished by partially filling the tank so that the work holders. will be alternately immersed in the treating liquid and removed therefrom. This wil have not merely the efi'ect of slowing down the outflow of treating fluid but may in some cases assist the washing action by drawing air through the work.

The means for fastenin the work-holder to thecarrier (shown in E igs. 5 to 8) form the subject matter of appllcation Ser. No.
